Cobweb — Minecraft block

Cobweb

Spider-spawned decoration found in mineshafts and strongholds that drastically slows any entity moving through it, useful for traps and mob control.

Description

Cobweb is found naturally in abandoned mineshafts, stronghold corridors, and igloo basements. It can be obtained with shears, which give one intact block, or with a Silk Touch sword or tool, which also drops it intact. Without Silk Touch, breaking it with a sword drops string, while other tools destroy it without drops.

Any entity passing through it has its movement speed reduced to roughly 15% of normal, making it highly effective as a trap layer or mob-slowing barrier. Entities do not take fall damage while within it. Arrows shot through it slow to a crawl and may lose flight trajectory.

Players use cobwebs for mob farms to slow enemies before killing mechanisms, in PvP traps, and in adventure-map puzzle design. Decoratively, cobwebs create haunted-house aesthetics and are essential for abandoned-structure builds. String, crafted from this block, is a core ingredient for bows and fishing rods.

Java & Bedrock Guide

How to collect and use Cobweb in Minecraft

  1. 1

    Find natural cobwebs

    Explore abandoned mineshafts, stronghold corridors, igloo basements, and woodland mansions, where Cobweb generates naturally in clusters.

  2. 2

    Harvest the block intact

    Break Cobweb with shears or a Silk Touch tool to collect the block itself; a plain sword drops string instead, and other tools destroy it with no drop.

  3. 3

    Slow mobs and players

    Place Cobweb in mob-farm chutes, PvP traps, or narrow doorways to cut any entity's movement to roughly 15% of normal speed.

  4. 4

    Remove unwanted cobweb

    Pour water over Cobweb or set it alight to clear it instantly, which is faster than breaking each block by hand.

Edition note

Cobweb behaves the same in Java and Bedrock Edition and cannot be crafted in survival — collecting it always requires shears or Silk Touch.
